drm/msm/a5xx: really check for A510 in a5xx_gpu_init

[ Upstream commit 736a932736 ]

The commit 010c8bbad2 ("drm: msm: adreno: Disable preemption on Adreno
510") added special handling for a510 (this SKU doesn't seem to support
preemption, so the driver should clamp nr_rings to 1). However the
gpu->revn is not yet set (it is set later, in adreno_gpu_init()) and
thus the condition is always false. Check config->rev instead.
